title: [Epidemiology of children's intestinal parasitism in the Guadalquivir Valley, Spain].
abstract: BACKGROUND
  Intestinal parasitism represents a public health problem that should be periodically assessed in each region. In the present paper, a study about prevalence of intestinal parasites, has been carried out in children from the natural region of the Guadalquivir Valley.
  
  
  METHODS
  During the period 1994-1996, 1,917 children without symptoms, aging between 6 and 10, were studied by means of coprological analysis and Graham method, all of them living in 20 villages in the Guadalquivir valley.
  
  
  RESULTS
  The overall prevalence of intestinal parasitism have been of 27.12%. The reported parasites and their prevalence are as follows: Enterobius vermicularis (20.44%), Giardia lamblia (5.05%), Entamoeba coli (2.45%), Endolimax nana (1.61%), Entamoeba histolytica (0.31%), Entamoeba hartmanni (0.05%), Iodamoeba bütschlii (0.05%).
  
  
  CONCLUSIONS
  The overall prevalence of intestinal parasites is similar to that found in other spanish region, if only a little bit more favourable probably due to the long lasting drought and the improvements in health resources, no geohelminths have been detected unlike other protozoan infections, giardiasis maintains a relatively high prevalence.
